Patent CA-2212020-A1 (CA)
Title: Agricultural hopper
Inventor: BODIE CAMERON D
IPC: A01C15/00
Filed: 1997-08-01
Abstract: A multi-compartment tank structure for an agricultural air cart is formed in a modular configuration with two, three or more containers operable to carry different supplies of materials to the field. Each container is formed with an interlocking mating wall structure having a pair of spaced apart lobes separated by a curved key portion recessed with respect to the lobes. One container has a convex mating wall configuration interfits with another container having a complementary concave mating wall structure. In the three or more compartment configuration, the interior container is provided with both convex and concave opposing mating walls to cooperate with the adjacent containers. The lobes are formed from a number of planar surface segments. The bends and angles of the lobes coupled with the recessed curved key portion creating a rib provides adequate strength to resist bucking forces even when only one of the containers is utilized with material stored therein. A  ladder is provided adjacent the concave key portions on the interior of the container to provide yet greater resistance to buckling for the concave mating walls.

Title: Cancer metastasis inhibitor containing a streptococcus agalactiae ia type or ib type surface polysaccharide as a main ingredient
Inventor: KAWASE MITSUO
IPC: A61K35/74
Filed: 1995-12-27
Abstract: The present invention relates to the technology for inhibiting the cancer metastasis, and is aimed at the provision of a pharmaceutical composition for effectively inhibiting the metastasis of the cancer.      A cancer metastasis inhibitor according to the present invention is characterized by containing a sugar chain separated from a surface of a Streptococcus agalactiae Ia type or Ib type as a main ingredient. Since the surface sugar chains of the Streptococcus agalactiae Ia type or Ib type have structures similar to surface sugar chains of the cancer cells, the former surface sugar chains adhere to E-selectin appearing in an intravascular endothelial cell, competitively inhibit the adhesion between intravascular endothelial cells and the cancer cells, and effectively prevent of the metastasis of the cancer, when the sugar chains exist in blood of a patient.

Title: Improved urea synthesis process and apparatus therefor
Inventor: FUJII HIDETSUGU
IPC: B01J19/00
Filed: 1997-10-06
Abstract: A vertical condenser is installed on or above a urea synthesis column to condense the mixed gas from the stripper by bringing it into contact with an absorption medium under cooling.  A first down pipe for making the top part of the condenser communicate with the bottom part of the synthesis column is provided to allow the resultant condensate to flow down to the bottom part of the synthesis column by gravity. The condensate is subjected to area synthesis together with feed ammonia or a part of feed carbon dioxide supplied thereto.  The urea synthesis solution thus formed is introduced into the stripper by gravity through a second down pipe having an opening in the top part of the synthesis column.  Unreacted ammonia and carbon dioxide are separated as the aforesaid mixed gas by the rest of the feed carbon dioxide and introduced into the bottom part of the aforesaid condenser so as to be condensed.  Alternatively, the condensate form the vertical condenser is sucked by means of an ejector fluid, so that it is introduced into the bottom part of the urea synthesis column and is subjected to urea synthesis.

Title: Flexible light pipe for side-lit applications
Inventor: HALLDEN-ABBERTON MICHAEL PAUL
IPC: B29C48/30
Filed: 1997-10-31
Abstract: An improved optical light pipe for side-lit uses is formed from a core/cladding combination, optionally with a transparent jacket, where the core is preferably a cured acrylic polymer and the cladding is preferably a fluorocarbon polymer containing a very low level of fine particles which scatter the light uniformly along the length of the piping. Further light enhancement can be obtained with low levels of glass fibers or glass microspheres also present in the cladding. Chopped glass fibers alone at low levels in the cladding are useful for back-lit applications. The light pipe so formed is useful in signs, underwater outlines, corridor lighting in theaters, and similar uses.

Patent CA-2237205-A1 (CA)
Inventor: PATTERSON RALPH A
IPC: G01C19/72
Filed: 1998-05-08
Abstract: The invention is a method and apparatus for quantitatively characterizing the pressure induced nonreciprocity of a fiber-optic coil where the pressure-induced nonreciprocity is a property of a fiber-optic coil which pertains to the degree to which light beams, initially in phase, differ in phase as a result of traversing the fiber-optic coil in reverse directions while the fiber-optic coil is being subjected to a time-varying pressure. The method comprises the steps of applying time-varying pressure to the fiber-optic coil for a predetermined time period, measuring the phase difference of light beams traversing the fiber-optic coil in reverse directions during the predetermined time period, and obtaining a measure of the nonreciprocity of the fiber-optic coil utilizing the measured phase difference. If the time-varying pressure is specified by a first function of time, the measure of the nonreciprocity is the integral over the predetermined time period of the product of a second function of time and either (1) the phase difference of light beams traversing the fiber-optic coil in reverse directions during the predetermined time period or (2) the integral over time of the phase difference. The second function is chosen such that the measure of the nonreciprocity has a signal-to-noise ratio of at least one. Preferably, the second function is (1) an approximation of the time derivative of the first function if the product involves the phase difference or (2) an approximation of the first function if the product involves the integral of the phase difference. The invention also includes the apparatus for practicing the method.

Inventor: MANGNUS PETRUS JOSEPHUS
IPC: B01J37/24
Filed: 1996-11-28
Abstract: The invention pertains to a process for preparing an activated catalyst composition in which a catalyst composition comprising a Group VIII noble metal and a hydrocarbon-substituted aluminium compound on an alumina carrier containing up to 20 wt.% of other components is activated by being contacted with a hydrogen-containing gas at a temperature in excess of 500 °C, with the proviso that at least when he hydrocarbon-substituted aluminium compound present in the catalyst composition is not a hydrocarbon-substituted aluminium halide, he catalyst composition to be activated is contacted with a halogen compound either prior to or during the activating step. The catalyst obtainable by this process and the use thereof in hydrocarbon conversion processes, such as isomerisation and alkylation processes, are also part of the present invention. The effect of the high-temperature activation step is that the activity of the thus obtained catalyst is improved in comparison with a catalyst of the same composition which has not been subjected to said high temperature activation step.

Title: Process for treating wood
Inventor: BERGERVOET ANTHONY J
IPC: B27K5/04
Filed: 1997-02-27
Abstract: A process for treating wood involving impregnation of the wood with a preservative followed by the heat-fixation of the preservative in the wood using a pre-heated aqueous heat tansfer fluid to effect the heat fixation of the preservative. The process particularly relates to steps which are taken to reduce the level of any contamination of the aqueous heat transfer fluid resulting from any wood extractives, any unfixed preservative and/or any particulate matter (i.e. "sludge") that may be present in the fluid. The contamination is preferably reduced by incorporating in the heat transfer fluid an oxidant which will preferentially oxidize any wood extractives resulting from the contact of the treated wood with the fluid without any significant reaction occurring between the oxidant and the preservative.  Useful oxidants include inorganic chlorate salts such as sodium chlorate.
